Gatekeeping and the process of assessing student suitability for social work education is increasingly being impacted by the rapid growth of online programs. It remains unclear if suitability concerns within social work programs are operationalized differently between traditional and online/hybrid programs. This quantitative study used previously established student suitability constructs of social consciousness, ethical suitability, practice suitability, and personal suitability to examine attitudes of social work educators and administrators regarding gatekeeping in their respective online/hybrid and traditional social work programs. The study utilized a multivariate multilevel regression analysis to investigate the effect of participant background characteristics regarding perceived emphasis on gatekeeping within participant's own programs. Findings showed a large discrepancy between what was important to participants and what was perceived to be emphasized in their respective programs regarding suitability and gatekeeping. This study suggests that social work faculty and administrators need to pay particular attention to uneven gatekeeping practices related to technological and pedagogical shifts in the evolving social work education landscape.

Objective. Currently, the summaries of research on periodontal ligament stem cells (PDLSCs) are mainly reviews, and the systematic evaluation of all relevant studies is lacking. The aim of our study was to reveal the research status and developmental trends of PDLSCs using bibliometric analyses. Methods. Publications on PDLSC from 2004 to 2023 in the PubMed database were searched and then screened according to certain inclusion and exclusion criteria. Two researchers browsed the included papers and recorded information such as the research type and research model. The VOSviewer software was used to analyze the distribution of authors, journals, and institutions. The contents and directions of PDLSC research were summarized by analyzing high‐frequency keywords. The CiteSpace software was used to monitor burst words, determine hot factors, and indicate developmental trends. Results. During the past two decades, the number of studies on PDLSCs increased. China published the most related papers. The primary type of article was basic research. Among core journals, the Journal of Periodontal Research had the highest number of publications. The Fourth Military Medical University (China) was leading in the number of articles on PDLSCs. Research topics mainly included mechanism of periodontal diseases, tissue engineering and regeneration, biological characteristics of PDLSCs, and comparison with other stem cells. Infectious inflammation and mechanical stimulation were important pathological conditions and research topics. Conclusion. The research of PDLSCs is still in a rapid development stage. Our study provides new insights into the current research status and future trend in this field. [ABSTRACT FROM AUTHOR]

Purpose: With the increasing need for well-­-prepared and leading practitioners in the field of education as well as the renewed efforts to further distinguish the EdD from the PhD in higher education in recent years, the curriculum of EdD programs nationwide has been questioned and criticized for its disconnection from the needs of leading practitioners and schools. The primary purpose of this study is to examine the practical relevance of the coursework of EdD programs in PK-­12 school leadership. Methods: Three hundred and forty-two principals from California public schools, and 43 EdD program graduates and 38 doctoral faculty members from the California State University system participated in this study. A survey instrument developed on the basis of ISLLC 1996 and ISLLC 2008 was used to measure respondents' perceived importance of the knowledge, skills, and values for effective school leadership and the extent to which they were included in the EdD coursework. MANOVA and discriminant analysis were conducted to answer the specific research questions. Findings: Results indicate that the curriculum of the EdD leadership programs lacks practical relevance. In practice the EdD has not been differentiated from the PhD with respect to the coursework. Implications: The practical relevance of the coursework should be considered in the assessment and evaluation of the quality or effectiveness of an EdD program, and used to distinguish the EdD from the PhD. The findings add empirical evidence to the renewed debate over the distinction between the EdD and the PhD, and spur revitalization of the EdD.

Optimizing the design of the conformal cooling channel can increase the cooling rate of injection mold. The aim of this study was the problem of low cooling efficiency of injection mold for deep-cavity plastic parts under the conventional cooling channel. Based on the analysis of the heat transfer principle of the injection mold, a mathematical description of the cooling time of the conformal cooling channel was made. By designing orthogonal experiments and using simulation methods in the Autodesk Moldflow 2019 software, with the minimum cooling time of the mold as the optimization goal, experimental optimization was carried out for the three design variables of the channel, thereby obtaining the optimal combination of design variables for the conformal cooling channel. The conformal cooling channel layout was innovatively designed, and through computer simulation experiments, it was concluded that the conformal cooling channel adopted a series flat-head layout, which has the shortest cooling time and the fastest cooling rate. Metal additive manufacturing technology was used to complete the manufacturing of the mold insert with the conformal cooling channel. After the trial production of the conformal cooling injection mold, the molding cycle was obviously shortened, and the injection molding production efficiency was significantly improved.

To study the relevant factors affecting corporate financial fraud and the interaction between factors, this paper extracts 19 factors affecting corporate financial fraud from 5 aspects. Then it divides the hierarchy using the interpretative structural modeling (ISM) respectively to clarify the logical relationships and calculate the values of dependency and driving force jointly with the Fuzzy MICMAC (MICMAC) to categorize the indicators affecting financial fraud. We found that: 6 indicators, such as profit and tax mismatch, are the key factors influencing corporate financial fraud and will directly lead to fraud; 6 indicators, such as income and long-term asset variation, have a high degree of correlation with other indicators and a wide range of influence on fraud; 7 indicators such as excessive managerial power, have a low probability of being influenced by other factors but have a higher probability of influencing other factors. Combining the research results with the actual situation, we finally provide suggestions for solving corporate financial fraud from 3 perspectives.
